DISK AND COLTER HOLDER.

SPECIFICATION forming part of Letters Patent No. 776,585, dated December 6, 1904.

Application filed March 29, 1904.

To all 'La7/wm, t may concern:

Be it known that I, JOHN DURKEE, residing at Voodbine, in the county of Harrison and State of Iowa, have invented certain useful Improvements in Disk and Colter Holders; and I do hereby declare that the following is afull, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specilication.

This invention relates to a new andnovel improvement in disk and colter holders.

The aim of my invention is to provide a simple device adapted to be attached to a suitable emery-stand, so arranged that the holder will receive a disk of any size which may be adjusted to the holder and be held adjacent the emery-wheel in such a manner that any desired bevel or cutting edge may be provided, the device further being neat and simple of construction. Y

In the accompanying' drawings I have shown in Figure 1. a top view of the emery-stand, disclosing a holder secured and held adjacent a suitable emery-wheel. Fig'. 2 discloses an enlarged detail of the journal securing the disk-holding shaft. Fig. 3 discloses an elevation of the swinging holder as used in my invention, while Fig. 4 discloses a detail of the end of the disk-holding shaft.

In carrying out the aim of my invention I useany suitable emery-stand of any suitable height and provided with the usual base-frame 2, by means of which the stand is secured to the floor, and which emery-stand above is provided with the head 8, having the bearings 4, supporting the main driving-shaft 5, provided with the belt-pulley 6, adapted to receive a suitable driving-belt, while to one end of this shaft 5 is secured a suitable emery-wheel 7 Secured to the stand 1 'is the collar-bearing 9, held by means of the strap 8, secured by the bolts a, and Working' within this collarbearing 9 is a holder in the form of a doubleended crank-rod 10, provided with the upwardly-extending stub-shaft 12, to which is Serial No. 200,659. (No model.)

secured the supporting-collar b, while the stub-shaft end 13 is fixed with the stop-collar c, as clearly shown in Fig. 3.

The shaft 5 is adapted to be revolubly held within the collar-bearing 9 to swing freely thereon, while the stub-shaft 12 is adapted to removably and revolubly receive the head A of the operatingdever 14, this head A being provided with the bearing 15, adapted to revolubly secure the hub 23, through which extends and within which is held in a fixed condition the shaft B, having the square shoulder end 17, terminating in the threaded end 19, and further boing provided with the shoulder 18, between which end the retaining-nut 21 of which is held the washer 20, operating against the end of the bearing 15, the hub 24 being provided with a shoulder fn, as shown in Fig. 2, to insure the bearing 15 to be snugly held between the shoulder c and washer 20. At the remaining end the shaft B is provided with the square end 16, this end also being' threaded to receive the nut 25, and interposed between the hub 24 and the nut 25 are held the disks the outer one of which is to be sharpened. Interposed between the two disks is the preferably felt pad e, which is merely used to determine the sound, a second or inner disk a' being used as a holder for the pad. Where no pad is used, the disk is apt to vibrate and make considerable noise. Now when it is desired to sharpen and bevel the edge of the outermost disk a suitable power is applied to the pulley 6 to rotate the emery-wheel 7,

when the operator grasps the operating-lever 14 and fixes a crank-handle 26 to the end of the shaft B and rotates the disk to provide the disk with the proper bevel or sharpening edge. The tension under which the disk is brought against the ernery-wheel is regulated by means of the lever 14, the disk :n being' turned to bring the cutting' edge successively in front of the emery-wheel.

As the holder 10 swings freely inward and outward, it is of course understood that any sized disk-plate or rolling colter can be ground, and

Having thus described my said invention,

same, a nut securing said Xed shaft at one end, said nut projecting beyond said hub to revolubly secure said hub Within said leverbearing, lsaid hub being provided with a liaring neel; portion, said fixed shaft being adapted to receive a suitable disk, and a crank to rotate said shaft, all arranged substantially as and for the purpose set forth.

In testimony whereofl I aliix my signature in presence of tivo Witnesses.

JOHN DURKEE. /Vitnesses:
